Zoro Select 1-1/2" FNPT Forged Steel Union

This union connects two lengths of 1-1/2 inch female NPT pipe using a forged steel body with a black oxide finish. It is rated for Class 3000 service in plumbing and industrial piping systems. The component suits installers who need a strong, separable joint for black steel pipe networks.

Verify thread size and pressure rating before

Confirm that both mating pipes use 1-1/2 inch female NPT threads with an 11-1/2 thread pitch to match the union ends. Ensure the system design pressure does not exceed the Class 3000 rating for forged steel fittings. Check that the black oxide coating is compatible with the intended fluid and environment.

Forged steel construction handles sustained

The solid forged body resists deformation under continuous Class 3000 working pressure better than cast alternatives. Black oxide provides baseline corrosion resistance during long-term exposure to air and moisture. The union design allows repeated disassembly for maintenance without damaging pipe threads.
